White LED Driver
with Synchronous Boost Converter
and PWM Brightness Control for up to 4 LEDs in Series
BD6076GUT
General Description
The BD6076GUT is a white LED driver IC with
synchronous rectification that can drive up to 4LEDs.
With synchronous rectification (no external schottky
diode required) and small package, they can save
mount space.
And the brightness of LED can be adjusted by using
PWM pulse on EN pin.
